我有从 Linkedin 提取我的连接信息的工作代码。但是，每当我尝试拉位置时，我都会得到奇怪的结果。

此代码有效，但您会看到“object OBJECT”应该在哪里。

<html lang="en">
<head>
<title>LinkedIn Industries</title>
<script type="text/javascript" src="http://platform.linkedin.com/in.js">
api_key: xxxxxxx
onLoad: onLinkedInLoad
scope: r_network,r_emailaddress,r_fullprofile,r_basicprofile,r_contactinfo

</script>
</head>
<body>




<p>This example demonstrates how to retrieve a user's connections.  It also uses the LinkedIn auth events (load, login, logout) to control behavior.</p>

<!-- NOTE: be sure to set onLoad: onLinkedInLoad -->
<script type="text/javascript">
function onLinkedInLoad() {
  IN.Event.on(IN, "auth", function() {onLinkedInLogin();});
  IN.Event.on(IN, "logout", function() {onLinkedInLogout();});
}


function onLinkedInLogout() {
  setConnections({}, {total:0});
}

function onLinkedInLogin() {
  // here, we pass the fields as individual string parameters
  IN.API.Connections("me")
    .fields("id", "firstName", "lastName", "pictureUrl", "publicProfileUrl","location:(name)")
    .result(function(result, metadata) {
      setConnections(result.values, metadata);
    });
}

function setConnections(connections) {
  var connHTML = "<ul>";
  for (id in connections) {
    connHTML = connHTML + "<li><a href=\"" + connections[id].publicProfileURL + "\">";

    /* picture url not always there, must be defensive */
    if (connections[id].hasOwnProperty('pictureUrl')) {
      connHTML = connHTML + "<img align=\"baseline\" src=\"" + connections[id].pictureUrl + "\"></a>";
    }  else {
      connHTML = connHTML + "<img align=\"baseline\" src=\"http://static02.linkedin.com/scds/common/u/img/icon/icon_no_photo_80x80.png\"></a>";
    }

    connHTML = connHTML + "&nbsp;<a href=\"" + connections[id].publicProfileUrl + "\">";
    connHTML = connHTML + connections[id].firstName + " " + connections[id].lastName + "</a>";
    connHTML = connHTML + " (Location: " + connections[id].location + ")</li>";
  }

  connHTML = connHTML + "</ul>";
  document.getElementById("connectionsdata").innerHTML = connHTML;
}
</script>
<script type="IN/Login">
<div id="connectionstest">
  <p>Current User's Connections:</p>
  <div id="connectionsdata"></div>
</div>
</script>
</body>
</html>

主要问题确实存在于位置，在文档中这应该替换为 location.name，但是，每当我这样做时，我什么也得不到，尽管我可以看到有一个带有 json 的 XHR 响应，它具有：

位置：{“名称”：“都柏林等”}

请帮忙解开隐藏位置之谜

由于错误消息建议您在实际尝试显示字符串时显示对象。因此，您需要选择该对象的正确属性：

connHTML = connHTML + " (Location: " + connections[id].location.name + ")</li>";

也许您可以将代码设置 html 临时替换为连接数组真正包含的内容的日志：

//connHTML = connHTML + "&nbsp;<a href=\"" + connections[id].publicProfileUrl + "\">";
//connHTML = connHTML + connections[id].firstName + " " + connections[id].lastName + "</a>";
//connHTML = connHTML + " (Location: " + connections[id].location + ")</li>";
console.log(connections[id]);

当您记录一个对象时，您可以单击它来检查它的属性，也许有些项目根本不包含位置。在这种情况下，您可以尝试：

function setConnections(connections) {
  var connHTML = "<ul>",
  tmpLocation;
  .....
  tmpLocation= (connections[id].location && connections[id].location.name)
    ?connections[id].location.name:"Unknown";
  connHTML = connHTML + " (Location: " + tmpLocation + ")</li>";
